BARREL-HEAD.

Specification of Letters Patent.

Patented Feb. 20,1917.

Application led June 18, 1915. Serial No. 34,832.

To all 'whom t may concern.'

Be it known that I, HARTLEY ELLIS, a citizen Vof the United States, anda resident of Cleveland, in the county of Cuyahoga and State ofOhio,have invented certain new and useful Improvements in Barrel-Heads, ofwhich the following is a specification.

My invention relates to improvements in barrel heads, and it consists inthe combina# tions, constructions, and arrangements herein described andclaimed. Y y l Anobject of my invention is to provide a barrel headwhich may be removed from the barrel, thereby permitting ready access tothe interior.

A further object of my invention is to provide a barrel head vwhich isespecially adapted for steel barrels or other receptacles containingliquids, such as paint or varnish, and having means for locking the vhead to the barrel and Vfor unlocking it when it is desired to haveaccess to the con-y tents of the barrel.

A further object of my invention is to provide a head for steel barrelswhich will stand great pressure and yet which may be readily removed andreplaced.

Other objects and advantages will appear in the following specification,and the novel features of the device will be particularly vapointed outin the appended claims.

My invention is illustrated in the accompanying drawings forming a partof this application in which- Figure 1 is a sectional view through thehead.

Fig. 2 is a plan view. p

Fig. 3 is an enlarged section of a portion of the head.

Fig. 4L is a section through the locking mechanism of the head.

Fig. 5 is a plan view of the part shown in Fig. 4. v

Fig. 6 is a plan view of one of the cam plates. i

Fig. 7 is a perspective view of one of the locking plates.

In carrying out my invention I make use of any suitable body portion. InFig. 1 I have shown a body portion 1 which is of steel and to which issecuredon the upper interior edge, a ring. This ring is preferablywelded to the steel body portion 1. The ring consists of a base portion2 having an annular shoulder 3 and being provided with an annular grooveor recess 4,

-of theplate I have shown at 12 and the cam the upper wall of the groovebeing tapered or beveled as shown at 5. rAs will be lseen from Fie. 3,the beveled wall 5 is carried by a portion 6 which extends inwardly,thisf portion being preferably welded to the member l as stated, andforming with the portion 2 an integral inwardly extending flangeprovided with a shoulder and a groove. The closure is shown at 7. servedthat it is concave on th-e outer side.

The edge of the closure is bent laterally as'`V I shown at 7a and isarranged to engage the upper portion of the inner part of the member 2and to abut the shoulder 3.

The locking ldevice for the closure 7 is best shown in Figs.` 4 to 7inclusive. It comprises a lower base plate 8, of circular shape, towhich is riveted a central disk or plate 9 having a peripheral flange 9xwhich is raised from the surface of the plate 8 and which is providedwith a shoulder Sly, thisshoulder forming'a bearing for a cam plate 10.The latter has four inclined cam surfaces 10a, and as stated isrotatable about the plate 9. This cam plate 10 is riveted or otherwisesecured to a larger cam plate 11 which is providedy with four cam slots11a which follow the contour of the cam surfaces 10EL asshown in Fig. 6.v

. In Fig. `7 I have shown one of the locking members. This consists of aplate which is really the segment of a ring and which has on its inneredge a cam flange.` vThe body flange at 12a. A pin 13 is arranged to eX-tend through the slots 11av in the member 11. Fach of these lockingplates 7 is provided with a series of parallel slots 12". Y The centralone of these slots lies on a radial line through the center of thelockingdevice as a whole, while the other two are parallel with thecentral slot. These slots are arranged to receive pins 14 carried by thebase 8. n A cover plate 15 is provided which has 109 a downwardlyextended peripheral iiange 15a and an innerA downwardly extending fiange15b. The cover 15, the cam plates 11v and 10, are provided withregistering openings 15, 11, and 10c, respectively, for the 195reception of the fingers 17CL wrench 17.

From the ioreoin' descri )tion of the of a spann er various parts of thedevice, the operation The 110 thereof may he readily understood. barrelis `filled with paint, oil, gasolene, or other material desired to beshipped, and I the closure '7 is placed in position,a gasket i8 is nowplaced over the abutting edges 7a and 3 of the closure and the shoulder'respectively, this gasket being of any suitable type but beingpfeferal.lifY wicking which has been treated with some material such aspitch to render the same leak-proof. The base plate 8 of the lockingmechanism is now laid on the gasket. The locking mechanism beingy in itsretracted position, Ythe spanner wrench 17 is inserted inthe alinedopenings l5", llc, and 10 and the wrench is turned, thus rotating thecam members l() and il about the plate 9 as a center. The plate l() willforce the locking Vmember 12 eutwardly owing to the engagement ofthe camsurfaces l0v of tue plate l() with the cam surfaces l2 of the platerille-beveled surface 12C of the locking member l2, see Fig. 3,V

engages the inclined surface and forces the locking 4member down againstthe gasket 18. Further movement of the locking member will cause thelatter to enter underneath the flange G so as to permanently lock thehead in position.

"l ow if the barrel should 'be left out in the sun and be heated up, anypressure of the gases which develop from the inside of the barrel, rwilltend to force the closure 7 outwardly, but being of concave shape itresists this pressure. Moreoven'the edge of the closure is forcedtightly against the shoulder 3 and this effectively prevents any furthermovement of the closure. lt will be noted that the locking plate ispositively held by means ofthe flange 6.

Now when it is desired to open the barrel, all that is needed is toinsert the spanner wrench and reverse the movement, whereupon vthe plateil in its rotation will draw oh the pin 13, thereby causing theretraction of the locking member l2 and permitting the closure 7 to beremoved. It will be observed that the retraction of the locking membersis simultaneous, so that the one movement effects the unlocking of thede vice. Y

Sinee'the locking niechaiiiisnr is composed of members which are heldtogether, there are in fact only two separate parts which constitute thebarrel head, that lis to say, the closure 7 and the locking mechanism asa whole, so that when the barrel is open these two parts may be placedaside and after the contents of the barrel is used,'they maybe replacedand the empty barrel returned to the point from which it was ori'ginally shipped.

lt will be seen at once that this device is especially desirable forthose liquids such as gasolene, and oils which tend to give off vaporsthat exet considerable pressure when heated. The head is made in such away that it will withstand enormous pressure and yet it may be readilyremoved or replaced.
